What is Cybersecurity?

Cybersecurity includes the technologies, methods, and practices designed to defend against cybersecurity threats and reduce their effects. Its goal is to defend individuals’ and entities’ systems, software, devices, confidential information. It also defends monetary resources against simple and annoying computer viruses.

Look around today’s world, and it’s evident that our daily life relies heavily on technology. The advantages of this shift include swift access to online information and the comforts introduced by advanced home automation and ideas such as the Internet of Things.

So, what is cyber security and how serious are cyber security threats these days? Read on and see.

What is Cybersecurity?

James Stanger, the Chief Technology Evangelist at CompTIA, describes cybersecurity as the “focus on defending digital assets, including internet, WAN, and LAN resources, used for information storage and transfer.”

Undoubtedly, these digital assets are at risk from hackers aiming to illegally acquire confidential data through data breaches. Therefore, a comprehensive understanding should encompass a continually updating array of tools aimed at defending private information from unauthorized entry. In this endeavor, the roles of individuals, procedures, and technology are all crucial in ensuring data security.

Why is Cybersecurity Important?

Living in a world where all devices are interconnected offers the prime benefit of ease. Whether it’s work tasks, scheduling social events, shopping, or booking appointments, our smartphones or gadgets make it all effortlessly achievable, making it an integral part of our lives.

However, with such accessibility comes the risk of malicious entities causing significant harm. Hence, cybersecurity measures are vital in defending our data and, by extension, our lifestyle.

Types of Cybersecurity

Cybersecurity can be divided into 7 different types:

Application Security

Application security involves the integration of various protective measures in a company’s software and services to counter a wide variety of threats. In this specific area, cybersecurity professionals are tasked with creating secure code, developing safe application structures, ensuring stringent data input verification, among other responsibilities, all aimed at reducing the likelihood of unauthorized adjustments or access to application assets.

Cloud Security

Cloud security relates to creating secure cloud architectures and applications for companies that use cloud service providers like Amazon Web Services, Google, Azure, Rackspace, etc.

Identity Management and Data Security

This category includes actions, structures, and procedures that facilitate the authentication and authorization of valid users to a company’s digital systems. It includes the utilization of solid data storage solutions to protect information, whether it’s being transferred or stored on a server or computer. Furthermore, this category emphasizes the application of authentication methods.

Mobile Security

With the growing reliance on mobile devices, mobile security has become increasingly crucial. This area focuses on defending both organizational and individual data housed on devices such as tablets, smartphones, and laptops against varied threats, including unauthorized access, device misplacement or theft, malware, and viruses. Furthermore, mobile security utilizes authentication methods and promotes user awareness to enhance protection levels.

Network Security

Network security includes both hardware and software solutions designed to shield the network and its infrastructure from unauthorized interruptions, and other actions. Efficient network security defends a company’s resources from various threats, whether they come from internally or externally.

Disaster Recovery and Business Continuity Planning

Not all threats are human-based. This subdomain covers processes, alerts, monitoring, and plans designed to help organizations prepare for keeping their business-critical systems running during and after any sort of incident (massive power outages, fires, natural disasters), and recovering lost operations and systems in the incident’s aftermath. 

User Education

Knowledge is power, and staff awareness of cyber threats is valuable in the cyber security puzzle. Giving business staff training on the fundamentals of computer security is critical in raising awareness about industry best practices, organizational procedures and rules, monitoring, and reporting suspicious. This category covers cyber security-related classes, programs, and certifications.

Types of Cyber Threats

Keeping pace with cybersecurity challenges is demanding. IT professionals assess a vast array of threats, but the list continuously expands. Nowadays, cyberattacks are a frequent occurrence. While some are minor and managed swiftly, others escalate rapidly, causing significant interruption. Every cyberattack demands prompt intervention and resolution.

Here is a list of common cyber threats:

Malware

This threat encompasses ransomware, spyware, viruses, and worms. It can install harmful software, block access to your computer resources, disrupt the system, or covertly transmit information from your data storage.

Ransomware

Ransomware is actually a type of malware. The difference here is that ransomware infects a network or steals confidential data and then demands a ransom (typically currency of some sort) in exchange for access to your systems.

Phishing Attacks

Phishing is just like it sounds. Hackers throw a line out there hoping that you’ll bite, and when you do, they steal sensitive information like passwords, credit card numbers and more. Phishing attacks usually come in the form of emails that look legitimate and encourage you to reply.

Botnets

This particularly malicious attack consists of extensive cyberattacks carried out by malware-infected devices controlled from a distance. Imagine a series of computers all manipulated by a single nefarious cyber operator. Even more concerning, once computers are compromised, they become integrated into the botnet network.

Conclusion

In the ever-evolving digital landscape, dealing with cybersecurity threats stands as the bedrock of defending our interconnected world. As we’ve explored in this article, cybersecurity includes a wide range of defenses, techniques, and strategies aimed at protecting digital assets from a myriad of threats. From personal devices to expansive organizational networks, the importance of solid plans to resolve cybersecurity threats cannot be exaggerated.
